Luminescent properties and recent progress in applications of lanthanide metal-organic frameworks

Lanthanide metal-organic frameworks (Ln-MOFs), which is composed of organic bridging ligands and Ln 3 + ions/clusters, is an important component of luminescent MOFs. Compared with transition metal ions, lanthanide ions have a higher coordination number and abundant coordination geometry. Moreover, LnMOFs have special characteristics such as good porosity, topological diversity, high surface area and highly adjustable structure. The energy transfer (ET) process in Ln-MOFs could be easily affected by the interaction between host framework and guest, resulting in the change of luminescence intensity or color. Over the past few decades, the features of Ln-MOFs open the door to a range of incredibly important applications. However, there are few reviews on systemic summary of the various applications of Ln-MOFs. In this paper, we summarized the latest progress of Ln-MOFs applications, including the Ln-MOFs in chemical and biological sensors, optical information devices and catalysis, respectively, and discussed design mechanism. The possible problems in current research are briefly prospected, hoping to provide some helpful guidance for the future development of Ln-MOF materials.
